Digital Cross Connect System definition

Digital Cross Connect System or "DCS" is a function which provides automated Cross Connection of Digital Signal Level 0 (DS0) or higher transmission bit rate digital channels within physical interface facilities. Types of DCS include but are not limited to DCS 1/0s, DCS 3/1s, and DCS 3/3s, where the nomenclature 1/0 denotes interfaces typically at the DS1 rate or greater with Cross Connection typically at the DS0 rate. This same nomenclature, at the appropriate rate substitution, extends to the other types of DCS specifically cited as 3/1 and 3/3. Types of DCS that cross connect Synchronous Transport Signal level 1 (STS-1 s) or other Synchronous Optical Network (SONET) signals (e.g., STS-3) are also DCS, although not denoted by this same type of nomenclature. DCS may provide the functionality of more than one of the aforementioned DCS types (e.g., DCS 3/3/1 which combines functionality of DCS 3/3 and DCS 3/1). For such DCS, the requirements will be, at least, the aggregation of requirements on the "component" DCS. In locations where automated Cross Connection capability does not exist, DCS will be defined as the combination of the functionality provided by a Digital Signal Cross Connect (DSX) or Light Guide Cross Connect (LGX) patch panels and D4 channel banks or other DS0 and above multiplexing equipment used to provide the function of a manual Cross Connection. Interconnection is between a DSX or LGX to a Switch, another Cross Connection, or other service platform device.

Digital Cross Connect System or “DCS” is as described in Attachment 3 of this Agreement.

Digital Cross Connect System means an electronic switching node that enables circuits to be cross-connected.

Examples of Digital Cross Connect System in a sentence

• They are: • Microwave Wireless Bridges – for Metropolitan Area Network connectivity in Karachi• Digital Cross Connect System (DXX)/High bit rate Digital Subscriber Line (DSL)- the Primary WAN medium and• Single Carrier Per Channel Very Small Aperture Terminal (VSAT) links – the additional WAN connectivity.

• AT&T-13STATE may reserve space for Switching, Power, Main Distribution Frame (MDF), and Digital Cross Connect System (DCS) up to anticipated customer growth over a ten (10)-year life expectancy of the ultimate footprint of the equipment.

• Appendix A prescribes “per DS0” and “per DS1” rates for multiplexing and “per channel” rates for Digital Cross Connect System (DCS) multiplexing.This is inconsistent with both Verizon’s existing rate structure and its existing practices, in which it provisions—and bills--UNE interoffice transmission facilities on a per-multiplexer basis.
